Good morning all,Just received an email from British Airways saying that our flights seats from Singapore have been changed due to operational reasons.On going to manage my booking, it appears that there are choices for both an upper deck as well as a lower deck. Flight number is BA0012 on the 9th of April, Singapore to London Heathrow. Am I to assume this is an airbus A 380? If so, what are the best world traveller seats to choose as right now I seem to have the pick of that cabin-we are a couple so like the idea of twin seats.

Many thanks in advance for all your wisdom.James.
